Technical Field

[0001] This application relates to the field of gas monitoring technology, and in particular to a detection component, detection device and detection system. Background Technology

[0002] Currently, the airflow in the intake and exhaust ports of the detection component is through a single ventilation hole. When the airflow from the exhaust port exits through the ventilation hole on the cover plate, it interferes with the airflow drawn in through the ventilation hole on the cover plate, thus interfering with gas detection and affecting detection accuracy.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] Therefore, it is necessary to provide a detection component, detection device, and detection system to address the problem that the airflow from the exhaust vent, when discharged through the ventilation holes on the cover plate, interferes with the airflow drawn into the intake vent through the ventilation holes on the cover plate, thereby interfering with gas detection and affecting detection accuracy.

[0005] Firstly, a detection component includes:

[0006] The housing has a receiving cavity and a housing air inlet and a housing air outlet communicating with the receiving cavity;

[0007] A detection module, wherein the detection module is disposed within the receiving cavity, and the first air inlet of the detection module is connected to the air inlet of the housing; and

[0008] A power module is disposed within the receiving cavity. The second air inlet of the power module is connected to the first air outlet of the detection module, and the second air outlet of the power module is connected to the air outlet of the housing.

[0009] In one embodiment, the housing includes an outer shell and a middle frame, the outer shell covering the middle frame, the outer shell having an air inlet and an air outlet, and the outer shell and the middle frame together forming the receiving cavity;

[0010] The middle frame is provided with a first placement slot and a second placement slot spaced apart along a first direction. The first placement slot is connected to the air inlet of the housing, and the second placement slot is connected to the air outlet of the housing. The wall of the first placement slot is provided with a connecting hole that is connected to the second placement slot. The detection module is located in the first placement slot, and the first air outlet of the detection module is connected to the connecting hole. The power module is located in the second placement slot.

[0011] In one embodiment, the middle frame is provided with a partition, which is located outside the first placement slot and the second placement slot and connected to the slot walls of the two slots. The partition divides the middle frame into a first side and a second side that are spaced apart along the first direction.

[0012] The detection module includes an electrically connected sensor and a circuit board. The circuit board has a through-hole. The sensor is located in the first placement slot. The circuit board is located on the first side and covers the first placement slot and the partition. The first air outlet of the sensor is connected to the connecting hole.

[0013] The outer casing located on the first side is provided with the casing air inlet, and is spaced apart from the circuit board along the first direction to form an air inlet chamber, the air inlet chamber being in communication with the casing air inlet and the circuit board air inlet;

[0014] The outer casing located on the second side is spaced apart from the partition to form an air outlet chamber, which communicates with the connecting hole and the second placement slot.

[0015] In one embodiment, the detection component further includes a first seal, which is disposed on the side of the circuit board away from the partition and located between the circuit board and the housing. The first seal covers the circuit board and is spaced apart from the circuit board along the first direction. The first seal has a through-hole for air inlet, which communicates with the housing air inlet.

[0016] In one embodiment, the outer casing located on the first side is further provided with the casing air outlet, which is spaced apart from the casing air inlet.

[0017] In one embodiment, the detection component further includes a second seal disposed on the second side of the partition and located between the partition and the housing. The second seal covers the first placement groove, the second placement groove and the partition, and forms the air outlet chamber between the second seal and the partition.

[0018] In a second aspect, there is a testing device comprising an assembly assembly and a testing assembly, wherein the testing assembly is the testing assembly described in the first aspect, and the assembly assembly is used to install the testing assembly onto a subject to be tested.

[0019] In one embodiment, the assembly assembly includes an assembly housing and a spacer. The assembly housing has an assembly receiving cavity and an inlet, an outlet, and an assembly opening communicating with the assembly receiving cavity. The detection assembly and the spacer are inserted into the assembly receiving cavity through the assembly opening. The spacer simultaneously abuts against the detection assembly and the assembly housing to cooperate with the detection assembly in blocking the assembly opening. The spacer is at least partially disposed between the housing air inlet and the housing air outlet. The inlet is used to communicate with the housing air inlet, and the outlet is used to communicate with the housing air outlet.

[0020] In one embodiment, the assembly housing includes a first side plate, a second side plate, a third side plate, a fourth side plate, and a bottom plate connected together. The first side plate, the second side plate, the third side plate, and the fourth side plate are all disposed on the bottom plate and are sequentially connected to form the assembly receiving cavity and the assembly opening. The first side plate and the third side plate are arranged with a gap between them, and the second side plate and the fourth side plate are arranged with a gap between them. The first side plate has the inlet, and the second side plate has the outlet.

[0021] The isolation component includes a first part and a second part that simultaneously abut against the detection component and the first side plate. The second part is connected to the middle of the first part, and their extending directions intersect. The first part blocks the assembly opening, and the second part is located between the housing air inlet and the housing air outlet.

[0022] Thirdly, a detection system includes a detection device and a subject to be detected, wherein the detection device is disposed on the subject to be detected, and the detection device is the detection device described in the second aspect.

[0023] The aforementioned detection component's housing has a receiving cavity, and separate housing inlet and outlet communicating with the receiving cavity. This design allows air intake and exhaust to occur through different openings, avoiding the situation in existing detection components where airflow from both the inlet and outlet passes through ventilation holes on the cover, thus preventing airflow from the exhaust port from interfering with the airflow from the intake port. The detection module is located within the receiving cavity, with its first air intake end communicating with the housing inlet. The power module is located within the receiving cavity, with its second air intake end communicating with the first air outlet end of the detection module, and its second air outlet end communicating with the housing outlet. This layout ensures that the airflow enters from the housing inlet, passes sequentially through the detection module and the power module, and finally exits from the housing outlet, forming an orderly airflow path. This guarantees stable airflow, reduces airflow interference between components, thereby improving the accuracy of gas detection and avoiding adverse effects caused by airflow interference.

Detailed Implementation

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] Cooking fumes are the large amount of thermal oxidation and decomposition products produced by cooking oil and food under high temperatures. During cooking, the oil is heated, and when the temperature reaches the smoke point of 170℃, initial decomposition produces blue smoke. As the temperature continues to rise, the decomposition rate accelerates. When the temperature reaches 250℃, a large amount of oil fumes are produced, accompanied by a pungent odor. The main components of cooking fumes are small oil droplets; small food particles; and aldehydes, ketones, hydrocarbons, fatty acids, alcohols, and aromatic compounds, collectively known as TVOCs. Cooking fumes are strongly correlated with respiratory diseases. Modern kitchens are usually equipped with exhaust systems to vent cooking fumes outdoors, thereby reducing the harm to human health.

[0038] Current range hoods use a detection component to detect cooking fumes. This component has an internal duct containing a fan that ensures continuous airflow from the intake to the exhaust. The intake and exhaust are located on the same side and have openings at the same horizontal level. The cover of the detection component has multiple ventilation holes, with the lower side of the cover attached to both the intake and exhaust. Each intake corresponds to at least one ventilation hole, and each exhaust corresponds to at least one ventilation hole. While this detection component can detect cooking fumes, the airflow to both the intake and exhaust passes through these ventilation holes. Therefore, the exhaust airflow passing through these holes interferes with the airflow drawn into the intake through the same holes, affecting the accuracy of the gas detection.

[0039] Please see Figure 1 and Figure 2 Based on the above problems, in a first aspect, embodiments of this application provide a detection component 10, which includes a housing 1, a detection module 2, and a power module 3. The housing 1 has a receiving cavity and a housing air inlet 11 and a housing air outlet 12 communicating with the receiving cavity; the detection module 2 is disposed within the receiving cavity. (See also...) Figure 1 The airflow direction is as follows: the first air inlet of the detection module 2 is connected to the air inlet 11 of the housing; the power module 3 is located inside the receiving cavity. Please refer to [link / reference]. Figure 2 The airflow direction is such that the second air inlet of the power module 3 is connected to the first air outlet of the detection module 2, and the second air outlet of the power module 3 is connected to the air outlet 12 of the housing. The housing 1 of the detection assembly 10 is provided with a receiving cavity, and independent housing air inlet 11 and housing air outlet 12 connected to the receiving cavity. This design allows air intake and exhaust to proceed through different openings, avoiding the situation where the airflow from the air inlet and exhaust both enter and exit through ventilation holes on the cover plate, as is the case with the current detection assembly 10, thus preventing the airflow from the exhaust port from interfering with the airflow from the intake port. The detection module 2 is located in the receiving cavity, with its first air inlet connected to the housing air inlet 11. The power module 3 is located in the receiving cavity, with its second air inlet connected to the first air outlet of the detection module 2, and its second air outlet connected to the housing air outlet 12. Please refer to... Figure 1 and Figure 2 This layout allows the airflow to enter through the housing inlet 11, pass through the detection module 2 and the power module 3 in sequence, and finally exit through the housing outlet 12, forming an orderly airflow path. This ensures stable airflow, reduces airflow interference between different parts, and thus improves the accuracy of gas detection, avoiding adverse effects on detection caused by airflow interference.

[0040] In an optional embodiment, the detection module 2 can be located inside or outside the air intake chamber 111. The power module 3 can be located inside or outside the air intake chamber 111. This application embodiment does not limit the location of the detection module 2 and the power module 3.

[0041] In an optional embodiment, the housing air inlet 11 and the housing air outlet 12 can be located on the same side or different sides of the housing 1.

[0042] In an optional implementation, the power module 3 may be a fan or an air pump, etc.

[0043] In an optional embodiment, the housing 1 can be a square housing, a cylindrical housing, or other shapes of housing.

[0044] Please see Figure 3 and Figure 4 In some embodiments, the housing 1 includes an outer shell 13 and a middle frame 14. The outer shell 13 covers the middle frame 14. The outer shell 13 is provided with a housing air inlet 11 and a housing air outlet 12. The outer shell 13 and the middle frame 14 together form a receiving cavity. The middle frame 14 is arranged along a first direction (e.g., Figure 3 and Figure 4The first placement slot 141 and the second placement slot 142 (shown in direction AA) are spaced apart and connected to each other. The first placement slot 141 communicates with the air inlet 11 of the housing, and the second placement slot 142 communicates with the air outlet 12 of the housing. The wall of the first placement slot 141 has a connecting hole 143 that communicates with the second placement slot 142. The detection module 2 is located in the first placement slot 141, and its first air outlet is connected to the connecting hole 143. The power module 3 is located in the second placement slot 142. The first placement slot 141 and the second placement slot 142 provide dedicated installation positions for the detection module 2 and the power module 3, allowing these two key modules to be installed in a modular manner. Initial installation and positioning can be completed simply by placing the detection module 2 into the first placement slot 141 and the power module 3 into the second placement slot 142, without the need for complex adjustments and calibrations, thus improving installation efficiency. The middle frame 14 integrates the installation structure, reducing the difficulty of directly installing the modules inside the outer casing 13. Compared to arbitrary installation within the housing cavity, the placement slots clearly define the installation positions of each module, making the assembly process clearer and simpler. The first placement slot 141 and the second placement slot 142 are spaced apart and connected by a connecting hole 143. This structural design separates the airflow paths for intake and exhaust. Airflow enters the first placement slot 141 from the housing inlet 11, passes through the detection module 2, enters the second placement slot 142 through the connecting hole 143, and finally exits from the housing outlet 12. This separation avoids mutual interference between intake and exhaust airflows, ensuring stable airflow within the detection assembly 10 and improving detection accuracy. The first and second placement slots 141 and 142 also provide a fixing function for the detection module 2 and the power module 3, preventing shaking or displacement of the modules during operation, further improving the stability of the detection assembly 10 and the accuracy of the detection results.

[0045] Please see Figures 3 to 5In some embodiments, the middle frame 14 is provided with a partition 144, which is located outside the first placement groove 141 and the second placement groove 142 and connected to the groove walls of both. The partition 144 divides the middle frame 14 into a first side 1441 and a second side 1442 spaced apart along a first direction. The detection module 2 includes a sensor 21 and a circuit board 22 electrically connected. The circuit board 22 has a circuit board air inlet 221 through it. The first air outlet of the sensor 21 is connected to the connecting hole 143. The sensor 21 is located in the first placement groove 141. Inside 41, circuit board 22 is disposed on the first side 1441 and covers the first placement groove 141 and partition 144; the outer shell 13 located on the first side 1441 is provided with a shell air inlet 11 and is spaced apart from circuit board 22 along the first direction to form an air inlet chamber 111, which communicates with the shell air inlet 11 and the circuit board air inlet 221; the outer shell 13 located on the second side 1442 is spaced apart from partition 144 to form an air outlet chamber 121, which communicates with the connecting hole 143 and the second placement groove 142. Partition 144 is located outside the first placement groove 141 and the second placement groove 142 and connects the walls of the two grooves, effectively separating the air inlet and air outlet areas. When the detection component 10 is working, the airflow entering from the housing inlet 11 passes through the inlet chamber 111 and the circuit board inlet 221 into the first placement slot 141 for detection. The airflow after passing through the detection module 2 enters the second placement slot 142 through the connecting hole 143, and then exits from the housing outlet 12 through the outlet chamber 121. The presence of the partition 144 avoids mutual interference between the inlet and outlet airflows, ensuring the independence and stability of the airflow path, which helps to improve the accuracy of the detection module 2 in detecting the oil fume components.

[0046] In an alternative embodiment, a sensor 21 may also be soldered onto the circuit board 22, with the sensor 21 mounted on the side of the circuit board 22 away from the partition 144.

[0047] In an optional embodiment, the sensor 21 may be a PM2.5 sensor 21, a TVOC sensor 21, or any combination of at least two or more of a carbon dioxide sensor 21, a carbon monoxide sensor 21, a methane sensor 21, a temperature sensor 21, or a humidity sensor 21.

[0048] Please see Figures 3 to 5When the power module 3 is a fan, for ease of installation, the outer frame of the fan is connected to the wall of the second placement slot 142, and the air inlet and outlet surfaces of the fan are spaced apart relative to each other along the first direction. To facilitate airflow from the detection component 10 in this embodiment, in some embodiments, the outer casing 13 located on the first side 1441 is also provided with a casing air outlet 12, which is spaced apart from the casing air inlet 11. It is understood that after the oil fume is detected by the sensor 21 of the detection module 2, it enters the connecting hole 143 from the first air outlet end of the sensor 21, and after entering the second placement slot 142 through the connecting hole 143, it is blown out by the fan towards the direction of the first side 1441 of the partition 144. By also placing the casing air outlet 12 on the outer casing 13 located on the first side 1441 of the partition 144, exhaust efficiency can be improved.

[0049] Please see Figure 4 In an optional embodiment, the detection assembly 10 further includes a connector 6. A socket 145 is provided through the middle frame 14, located on the side of the partition 144 away from the second placement slot 142. The connector 6 is fixed in the socket 145. The connector 6 is soldered to the circuit board 22. The connector 6 is used to connect electrical control lines, etc.

[0050] Please see Figures 3 to 5 In some embodiments, the detection component 10 further includes a first seal 4. The first seal 4 is disposed on the side of the circuit board 22 opposite to the partition 144 and is located between the circuit board 22 and the housing 13. The first seal 4 covers the circuit board 22 and is spaced apart from the circuit board 22 along a first direction. The first seal 4 has a through-hole 41, which communicates with the housing air inlet 11. The first seal 4 provides a sealing and protective function for the housing 1 located on the first side 1441 of the partition 144. The through-hole 41 of the first seal 4 communicates with the housing air inlet 11, allowing airflow to enter from the housing air inlet 11, flow through the seal 41 to the circuit board air inlet 221, and finally reach the detection module 2. This guiding effect makes the airflow more concentrated and stable, improving the efficiency and accuracy of the detection module 2 in detecting gas components.

[0051] Please see Figures 3 to 5In some embodiments, the detection assembly 10 further includes a second seal 5. The second seal 5 is disposed on the second side 1442 of the partition 144 and is located between the partition 144 and the outer shell 13. The second seal 5 covers the first placement groove 141, the second placement groove 142, and the partition 144, and forms an vent chamber 121 between the second seal 5 and the partition 144. The second seal 5 effectively fills the gap between the partition 144 and the outer shell 13 located on the second side 1442 of the partition 144, preventing the detected gas inside the detection assembly 10 from leaking into the external environment. This ensures that the gas can only follow a predetermined path, that is, from the first placement slot 141 through the connecting hole 143 into the second placement slot 142, and then through the outlet chamber 121 to be discharged from the outlet port 12 of the housing. This ensures the airtightness of the entire airflow circulation system and avoids the impact of gas leakage on the test results and the surrounding environment.

[0052] Secondly, please refer to Figure 6 This application provides a detection device 100, which includes an assembly assembly 20 and a detection assembly 10. The detection assembly 10 is as described in the first aspect. The assembly assembly 20 is used to install the detection assembly 10 onto the subject 200 to be tested.

[0053] In optional implementations, the subject to be inspected 200 can be an indoor space (range hood 2001 or furniture), a chemical plant, an oil and gas platform, a public facility, or a laser inspection site, etc. The application scenarios of the subject to be inspected 200 can cover fields such as industrial safety, environmental protection, public facilities, medical and health care, and emerging technologies.

[0054] Please see Figure 7In some embodiments, the assembly assembly 20 includes an assembly housing 201 and a spacer 202. The assembly housing 201 has an assembly receiving cavity 2011 and an inlet 2013a, an outlet 2014a, and an assembly opening 2012 communicating with the assembly receiving cavity 2011. The detection assembly 10 and the spacer 202 are inserted into the assembly receiving cavity 2011 through the assembly opening 2012. The spacer 202 simultaneously abuts against the detection assembly 10 and the assembly housing 201 to cooperate with the detection assembly 10 in blocking the assembly opening 2012. The spacer 202 is at least partially disposed between the housing air inlet 11 and the housing air outlet 12. The inlet 2013a is used to communicate with the housing air inlet 11, and the outlet 2014a is used to communicate with the housing air outlet 12. The assembly housing 201 forms a relatively independent assembly receiving cavity 2011, preventing the detection assembly 10 from being affected by external impacts or compression, and extending the service life of the detection assembly 10. Meanwhile, the housing 201 also provides a stable support structure for the detection component 10, ensuring that the detection component 10 remains stable during operation and will not shift or shake due to external vibrations or other factors, thereby guaranteeing the accuracy of the detection results. The isolator 202 is at least partially located between the housing inlet 11 and the housing outlet 12, which isolates the inlet and outlet air, preventing mutual interference between them. This avoids the detected gas in the outlet air mixing into the inlet air, ensuring the purity of the gas to be detected entering the detection component 10, and further improving the detection accuracy.

[0055] In an optional embodiment, the spacer 202 may be silicone or sponge, etc.

[0056] Please see Figure 7In some embodiments, the assembly housing 201 includes a first side plate 2013, a second side plate 2014, a third side plate 2015, a fourth side plate 2016, and a bottom plate 2017 connected together. The first side plate 2013, the second side plate 2014, the third side plate 2015, and the fourth side plate 2016 are all disposed on the bottom plate 2017 and are sequentially connected to form an assembly receiving cavity 2011 and an assembly opening 2012. The first side plate 2013 and the third side plate 2015 are arranged with a relative gap, and the second side plate 2014 and the fourth side plate 2016 are arranged with a relative gap. The plates 2016 are arranged at relative intervals. The first side plate 2013 has an inlet 2013a, and the second side plate 2014 has an outlet 2014a. The isolation member 202 includes a first part 2021 and a second part 2022 that simultaneously abut against the detection component 10 and the first side plate 2013. The second part 2022 is connected to the middle of the first part 2021, and their extension directions intersect. The first part 2021 blocks the assembly opening 2012, and the second part 2022 is located between the housing inlet 11 and the housing outlet 12. This arrangement can effectively isolate the inlet and outlet air, preventing mutual interference between them. It avoids the detected gas in the outlet air from mixing into the inlet air, ensuring the purity of the gas to be detected entering the detection component 10, and further improving the detection accuracy. Meanwhile, the second part 2022 can also guide the airflow, making the intake and exhaust flow more smoothly along the predetermined path.

[0057] Please see Figure 7 In an optional embodiment, the fourth side plate 2016 has a connector opening 2016a, which communicates with the insertion port 145 of the middle frame 14 to avoid the connector 6 in the detection assembly 10.

[0058] Please see Figure 7 In an optional embodiment, the assembly housing 201 is further provided with a latching part 2018, which protrudes from the third side plate 2015 and is used to limit the contact with the top of the detection component 10 to prevent the detection component 10 from coming out of the assembly housing 201.

[0059] In an optional implementation, the detection device 100 can be placed at any position on the subject 200 to be detected.

[0060] Thirdly, please refer to Figure 8 This application also provides a detection system 1000, please refer to the embodiments thereof. Figure 9 The detection system 1000 includes a detection device 100 and a subject 200 to be detected. The detection device 100 is disposed on the subject 200 to be detected. The detection device 100 is the detection device 100 as described in the second aspect.

[0061] Please see Figure 9 and Figure 10 In an optional embodiment, taking a fume extraction device as an example, the installation position of the detection device 100 is specifically described: The fume extraction device includes a range hood 2001 and an integrated stove 2002. The range hood 2001 is located above the integrated stove 2002 and is used to remove fumes. The range hood 2001 includes a main body 2003, a display module 2004, a main control module 2005, and a central processing unit. The main body 2003 has a housing cavity and a ventilation hole 2006 communicating with the housing cavity. The central processing unit, the main control module 2005, and the detection device 100 are all installed inside the housing cavity. The outlet 2014a and the inlet 2013a of the detection device 100 are both connected to the ventilation hole 2006. The display module 2004 is installed on the top of the main body 2003 and is used to display the monitoring data of the detection component 10, etc. The central processing unit is electrically connected to the display module 2004, the host control module 2005, and the connector 6 of the detection component 10 of the detection device 100. The real-time air quality data monitored by the detection component 10 is compared with the preset parameters.

[0062] Please see Figure 9 and Figure 10 In an optional embodiment, the detection device 100 may be fixedly connected to the main body 2003 of the machine by bonding, riveting or screwing.

[0063] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0064] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0065] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0066] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0067] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
